SHELBY, a citizen of theUnited-*Stateafand a resident of Globe, ifn. thgiioullty il Territory of Arizona, hayefinve'nte Structures, of which the-lvfollowingfis 'aff clear, and exactdescriptionf Ther purpose of the invention 1ste 'rovide a latch device especiallyV designed.. or norandto so construct t e'latch'tha'ti'tis simple, durable, economic, and-'readily applied and isv not liablejto get outjoforder:

Afurther pui' ose loli-the invention is to the bodyof the carisebroughttoits normalorcarrying-posltion- I f The inventlon. 'consists' in theV novel 'con'- parts,.as will be liereinafter'fully'set forth Reference is to he yhad to the accompanytion, in which similar characters of reference indicatecorresponding parts in Vall the fi lires. -Figure 1 is a perspective view of a 'umpTj ing-car and the improved latch Vapplied there? to. Fig. 2 is a lan view of a part of one side portion of the ody of the car and adjacent. plan view. of fthe improved device, anc Fig. 3y is a vertical section taken practically on the li'ne' 3f 3v of Fig.-2 A represents thefplatfprrnof. ai`dun1ping` body thereof, which Pedhgeneral'htOuI-l The Said body isfpmvidd' at its sidsswahf segmental projectlo'nsfll of which pro] y at actions' #cathare stream- Which 'projections rest@ I.

ast' the keeper O. The upper portion ofthe atch-'bar D normally. rests 1n the recess 16 of durable, ,and economic, is readily 'the latc can be attached to the rockin 1o'fthe car or to the platform and t event the keeper is attached tothe conear its top, and the web member 15 ofthe saidkeeper isprlovided atthe centralportion Nora of its outer edge. with a recess 16.", The said keeperj" inclined-inwardlyan'd in oppof ,ithe web member! li-ofthe v 6o ns from'the recess 16, as is lshownv y to the outer face of the channel track-bar I0 at that side ofthe vcar at which the keeper C is located, and the 'said latch-barD is madeas" with strength, is;- extends upward as possible consistent the keeper, to which recess it is snugly fitted,

thus holdingthe vbodylin its carrying posifff vAt the'uppe'lr endvof the latch-bar ahan A dle 19 isl attached, so that when the body- B is to be dumped by means of the handle 19,

the upper portion of the latch-har D may be sprung outward and disengaged from the keeper C, and as' the body.B is restored to its normal or carrying vposition the latchfbar D will slide along one or the other ofthe in clined edges 1K1 of the kee 'er until. it nds a -seat in the recess 16 ofthe eep er.y

Thislatch device 1s. exceedingly simple',

voperated `and eiective in operation It W-ill be understood that the 'spring-latch -and its keeper may be otherwise attached and located than shown-aas, for example,

the-latch'inay'be placed at any desired angle to the erpendicular ofthe device and that at in ing part;

3.*The combination with a car-platform and a rocking .body mounted to rock thereon, of a latch device consisting of a keeper T- shaped in cross-section, which keeper is se` cured to one side of the body, the 'outer edge of its web member being provided with a recess and having its surface inclined in opposite directions from the end portions of the said recess, anda latch consistin of a spring-bar secured at its lower end to tile platform, being otherwise free, the upper portion of which latch-bar normally fits in the recess of the said keeper,` and a handle at the upper end of the bar.

Ll. A platform, a dumping-body mounted to rock thereon, a keeper secured to one meniber and provided with a recess in its outer edge, the surface of the keeper bein inclined in opposite directions from the en( portions of said recess, and a latch-bar of spring material attached to the coperatmg member and normally engaging the lrecess 1n the kee er, the said dumpingbody being ada te( to rock in eithervdirection when the latc i-bar is disengaged from the keeper, the latch-bar automatically seating itself intlie recess of the keeper when the body is restored to its normal position.

In testimony whereof I have signed my name to this specification in the presence of two subscribing Witnesses.
